| Abstract | ||||
| BRASSICACEAE family includes a number of the most important Brassica cultivars such as canola, mustard and cabbage, and Arabidopsis thaliana as plant biology model species. Chromosome banding is the most probable protocol for karyotyping and to distinguish numerical chromosome abnormalities, duplications, inversions or deletions of chromosome parts, or exchanging a part from one to another chromosome as well. The aim of this study is to illustrate the DAPI banding patterns in 16 Brassicaceae species with small chromosome size, and they have different origin, ploidy level (chromosome number varies from 2n= 14 to 2n= 32). These species belong to five tribes (Brassiceae, Sisymbrieae, Lepidieae, Arabideae and Alyssea. The aim of this study is to illustrate the DAPI banding patterns in 16 Brassicaceae species with small chromosome size, and they have different origin and ploidy level (chromosome number varies from 2n= 14 to 2n= 32). In the current study we investigated different genera belong to five tribes of the family in regard to the position of regions as by using DAPI staining. It was excluded that most of plants with small chromosomes have mostly a centromeric bands and the more the chromosome size the more tendency to have interstitial bands. | ||||
